摘要
设计了一种基于RS 485总线的多点控制系统,充分考虑了构建RS 485总线控制系统时硬件及软件设计中的多种问题;给出了系统硬件原理图及通信协议;讨论了基于RS 485总线工控系统的一些常见问题及解决方法。该多点控制系统经实际应用证明通信可靠,整体性能符合工业现场要求。
A muhipoint control system is designed based on RS 485 bus. The problems in the hardware and software designs are given in perfect consideration. The circuit diagram and communication protocol are also given. At last some familiar questions in practice are discussed. This system has been used in practice, and its reliability and whole performance can meet the industral using.
